[CSharp] EasyChat

Description: 这是用C#做的一个简易的Windows平台下的聊天软件，包括了客户端和服务端的全部源码，注释很详细，有兴趣学习.net应用开发的同学可以下载来学习学习。这个示例包含了了C/S架构软件开发的很多基础知识和思想。 功能包括群发，私聊，发送震动，收到消息发声，闪屏提示等等，大致类似于QQ的多人聊天会话功能。 涉及到的知识主要包括： 1. TCP/IP通信，包括TcpClient , TcpListener , Socket , NetworkStream等几个用于TCP通信的类的实际应用。 2. WIN平台下的多线程程序开发，后台监听线程是网络应用程序开发中的一个基本技术，这个实例的客户端和服务器端都用了后台监听数据包的线程。 3. 客户端和服务器之间交换消息的方法，主要是byte[ ]格式的消息包的消息格式设计和识别,以便让客户端和服务器能够正确交互。 4. 服务端对连接客户的信息存储和状态监控，这个实例用了Hashtable来存储客户连接信息-a chat tool develop by c# in the desk of windows,including source code of client sever ,which can help the students who want to study .net and c#

[Internet-Network] network

Description: 程序为网络程序，应使用socket编程，服务器要实现对每一个访问的客户机发送一个欢迎消息，可选用select（）函数实现I/O多路复用，服务器通过socket相关函数来建立TCP连接，监听每一个访问的客户端，当有客户端向服务器发起连接时，将客户端文件描述符加入监听描述符集，客户端向服务器发送信息，同时也收到服务器发来的”Hello,Welcome Client！”。 本题需要写两个程序，分别是“server.c”和“client.c”。前者主要是在服务器端执行并等待客户端访问操作然后发欢迎信息，后者主要是向主机发送访问命令并接收服务器发来的欢迎信息。-Procedures for network programs, you should use socket programming, server to achieve for each visit to a client sends a welcome message, the choice of () function to achieve I/O multiplexers, server through socket correlation function to establish a TCP connection, monitor each client visit, when a client initiates a connection to the server, the client file descriptor join listening descriptor set, the client sends a message to the server, and also received a server sent Hello, Welcome Client !.

[Internet-Network] src

Description: a.确定本机的IP和端口，socket只有与某一IP和端口绑定，才能发挥其功能。 b.确定通讯协议：TCP 或 UDP。 编程步骤： a.建立一个套接字 b.绑定本机的IP和端口 c.如果是TCP，因为是面向连接的，要利用Listen()方法来监听网络上是否有人给自己发东西 如果是UDP，因为是无连接的，所以来者不拒。 d.TCP情况下，如果监听到一个连接，就可以使用accept来接收这个连接，然后就可以利用Send/Receive来执行操作了。而UDP，则不需要accept，直接使用SendTo/ReceiveFrom来执行操作。（注意，因为UDP不需要建立连接，所以在发送前并不知道对方的IP和端口，因此需要指定一个发送的节点才能进行正常的发送和接收） e.不继续发送和接收时使用close。-a. determine the machine s IP and port, socket only with an IP and port binding, in order to function. . b determine protocols: TCP or UDP. Programming steps: a. to establish a socket b. Bind the machine IP and port . c If TCP, because it is connection-oriented, and to take advantage of Listen () method to listen if anyone on the network to send their own thing if it is UDP, because it is not connected, so all comers. Under d.TCP case, if listening to a connection, you can use the accept to accept the connection, then you can use the Send/Receive to perform the operation. The UDP, you do not need accept, directly SendTo/ReceiveFrom to perform the operation. (Note that because UDP does not need to establish a connection, so before sending did not know each other s IP and port, so you need to specify a sending node can perform normal transmission and reception) e. not to continue sending and receiving using close.
